Gold Resource Corporation Reports Year-End 2014 Mineral Reserves

COLORADO SPRINGS, CO, United States, via ETELIGIS INC., 03/19/2015 – – Gold Resource Corporation (NYSE MKT: GORO) (the “Company”) announced year-end proven and probable mineral reserves of approximately 1,537,200 tonnes grading 7.21 grams per tonne precious metal gold equivalent (AuEq), or 356,100 ounces of precious metal gold equivalent ounces for its La Arista underground mine on the El Aguila Project. In addition to these reserves, the Company announced measured and indicated mineralized material totaling over 716,000 tonnes from the Switchback vein system, the Santiago vein and the Alta Gracia property. Gold Resource Corporation is a gold and silver producer with operations in Oaxaca, Mexico and exploration in Nevada, USA. The Company has returned over $102 million to shareholders in monthly dividends since commercial production July 1, 2010, and offers shareholders the option to convert their cash dividends into physical gold and silver and take delivery.

The updated report includes proven tonnes of 1,010,700 at 7.83 grams per tonne gold equivalent and probable tonnes of 526,500 at 6.01 grams per tonne gold equivalent, for a combined tonnage of 1,537,200 proven and probable reserves grading 7.21 grams per tonne precious metal gold equivalent. The report also estimates the recovery of significant base metals consisting of 7,194 tonnes (15.9 million pounds) of copper grading 0.6%, 18,938 tonnes (41.8 million pounds) of lead grading 1.6% and 40,828 tonnes (90.0 million pounds) of zinc grading 3.2% (based on 2014 actual average copper, lead and zinc recoveries of 78%, 77% and 83% respectively). Revenue generated from base metal sales is used to offset the Company’s cost of precious metal production.

In addition to and separate from the Arista mine, 716,900 tonnes of measured and indicated mineralized material was reported from three separate mineralized zones. The Switchback vein system, located 500 meters northeast of the Arista deposit, reported 448,600 tonnes in measured and indicated, grading 1.32 grams per tonne gold, 90 grams per tonne silver, 0.4 percent copper, 1.1 percent lead and 3.8 percent zinc. The Santiago vein, located directly northwest of the Arista deposit, reported 109,700 tonnes in measured and indicated, grading 1.81 grams per tonne gold, 135 grams per tonne silver, 0.2 percent copper, 0.5 percent lead and 1.0 percent zinc. Both of these mineralized zones are located on the Company’s El Aguila Project. The Alta Gracia property reported 158,600 tonnes, grading 0.57 grams per tonne gold and 339 grams per tonne silver. No appreciable base metals have been identified for the veins explored to-date at Alta Gracia.

The reserve report applies a new $110 per tonne Net Smelter Return (NSR) breakeven cutoff grade for its block model estimates. The NSR approach focuses on margin from all metals, as opposed to the prior report which applied a cutoff grade focusing only on gold and silver. Production goals and totals will remain in precious metal gold equivalent, while continuing to use base metals as by-product credits. With the continued decline in gold and silver market prices, Company management made the decision to switch to the NSR metric to maximize margins and more efficiently extract the greatest dollar value of all metals from each tonne of ore mined.

“We are very pleased with the Company’s 2014 El Aguila Project drill campaign and resulting year-end reserve update for the Arista mine,” stated Gold Resource Corporation’s CEO and President, Mr. Jason Reid. “Our exploration team in Mexico, led by our Vice President of Exploration Mr. Barry Devlin, had been tasked during 2014 with replacing tonnes mined during the year and they succeeded leaving the same three-and-a-half to four year mine life at the Arista mine, depending on future production levels.”

Vice President of Exploration, Mr. Barry Devlin stated, “Exploration efforts in 2014 at Arista continued to expand this robust polymetallic epithermal vein system. The Arista vein system has grown from just a few primary veins to over 27 veins and structures with further expansion potential. We expect to add additional tonnes and ounces with continued exploration. Equally important as the continued expansion at the Arista vein system, we have drilled three additional areas to an extent in which we were able to estimate measured and indicated mineralized material of 716,900 tonnes. With additional drilling and tighter drill hole spacing, we aim to establish reserves at these mineralized zones in the future. For 2015, our exploration goals include continued replacement of mined tonnes from Arista, expansion of known mineralized material zones from our exploration properties and discovery of new mineralized zones on our extensive property portfolio.”

Mr. Reid added, “We are very fortunate to have a polymetallic deposit at our El Aguila Project, which allows us flexibility in developing our mine plan. By adopting a Net Smelter Return approach, the Company is focused on margin and production of high quality tonnes and high-quality ounces, as opposed to chasing solely precious metal ounces for ounces sake which can often lead to leaving behind valuable base metals.”

As of December 31, 2014, our proven and probable reserves were:

In addition to our Proven and Probable reserves, we estimated measured and indicated mineralized material within the definition of Guide 7. Mineralized material does not have demonstrated economic viability.

As of December 31, 2014, our measured and indicated mineralized material was:

The cut-off date for data inclusion in the reserve report was December 31, 2014. All drilling, sampling and data collected since January 1, 2015, was excluded from the report. The proven and probable reserve report focuses entirely on the Arista deposit which remains open along strike and depth. The Company expects to add additional tonnes and ounces at Arista with infill, step-out and exploration drilling. The Company also expects to add to its mineralized material zones with infill, step-out and exploration drilling.
